-- **Full-stack**: Leptos can be used to build apps that run in the browser (_client-side rendering_), on the server (_server-side rendering_), or by rendering HTML on the server and then adding interactivity in the browser (_hydration_). This includes support for _HTTP streaming_ of both data (`Resource`s) and HTML (out-of-order streaming of `<Suspense/>` components.)
-- **Isomorphic**: Leptos provides primitives to write isomorphic server functions, i.e., functions that can be called with the “same shape” on the client or server, but only run on the server. This means you can write your server-only logic (database requests, authentication etc.) alongside the client-side components that will consume it, and call server functions as if they were running in the browser.
-- **Web**: Leptos is built on the Web platform and Web standards. The router is designed to use Web fundamentals (like links and forms) and build on top of them rather than trying to replace them.

-- **Fine-grained reactivity**: The entire framework is built from reactive primitives. This allows for extremely performant code with minimal overhead: when a reactive signal’s value changes, it can update a single text node, toggle a single class, or remove an element from the DOM without any other code running. (_So, no virtual DOM!_)

 This may be the big one: “production ready” implies a certain orientation to a library: that you can basically use it, without any special knowledge of its internals or ability to contribute. Everyone has this at some level in their stack: for example I (@gbj) don’t have the capacity or knowledge to contribute to something like `wasm-bindgen` at this point: I simply rely on it to work.

 On the surface level, these libraries may seem similar. Yew is, of course, the most mature Rust library for web UI development and has a huge ecosystem. Dioxus is similar in many ways, being heavily inspired by React. Here are some conceptual differences between Leptos and these frameworks:
 
 - **VDOM vs. fine-grained:** Yew is built on the virtual DOM (VDOM) model: state changes cause components to re-render, generating a new virtual DOM tree. Yew diffs this against the previous VDOM, and applies those patches to the actual DOM. Component functions rerun whenever state changes. Leptos takes an entirely different approach. Components run once, creating (and returning) actual DOM nodes and setting up a reactive system to update those DOM nodes.
-- **Performance:** This has huge performance implications: Leptos is simply _much_ faster at both creating and updating the UI than Yew is.
-- **Mental model:** Adopting fine-grained reactivity also tends to simplify the mental model. There are no surprising component re-renders because there are no re-renders. Your app can be divided into components based on what makes sense for your app, because they have no performance implications.
+- **Performance:** This has huge performance implications: Leptos is simply much faster at both creating and updating the UI than Yew is. (Dioxus has made huge advances in performance with its recent 0.3 release, and is now roughly on par with Leptos.)
+- **Mental model:** Adopting fine-grained reactivity also tends to simplify the mental model. There are no surprising component re-renders because there are no re-renders. You can call functions, create timeouts, etc. within the body of your component functions because they won’t be re-run. You don’t need to think about manual dependency tracking for effects; fine-grained reactivity tracks dependencies automatically.

 There are some practical differences that make a significant difference:
 
-- **Maturity:** Sycamore is obviously a much more mature and stable library with a larger ecosystem.
 - **Templating:** Leptos uses a JSX-like template format (built on [syn-rsx](https://github.com/stoically/syn-rsx)) for its `view` macro. Sycamore offers the choice of its own templating DSL or a builder syntax.
-- **Read-write segregation:** Leptos, like Solid, encourages read-write segregation between signal getters and setters, so you end up accessing signals with tuples like `let (count, set_count) = create_signal(cx, 0);` _(If you prefer or if it's more convenient for your API, you can use `create_rw_signal` to give a unified read/write signal.)_
+- **Server integration:** Leptos provides primitives that encourage HTML streaming and allow for easy async integration and RPC calls, even without WASM enabled, making it easy to opt into integrations between your frontend and backend code without pushing you toward any particular metaframework patterns.
+- **Read-write segregation:** Leptos, like Solid, encourages read-write segregation between signal getters and setters, so you end up accessing signals with tuples like `let (count, set_count) = create_signal(cx, 0);` _(If you prefer or if it's more convenient for your API, you can use [`create_rw_signal`](https://docs.rs/leptos/latest/leptos/fn.create_rw_signal.html) to give a unified read/write signal.)_
 - **Signals are functions:** In Leptos, you can call a signal to access it rather than calling a specific method (so, `count()` instead of `count.get()`) This creates a more consistent mental model: accessing a reactive value is always a matter of calling a function. For example:

+
+A new [version](https://doc.rust-lang.org/cargo/reference/resolver.html#resolver-versions) of Cargo's feature resolver was introduced for the 2021 edition of Rust.
+For single crate projects it will select a resolver version based on the Rust edition in `Cargo.toml`. As there is no Rust edition present for `Cargo.toml` in a workspace, Cargo will default to the pre 2021 edition resolver.
+This can cause issues resulting in non WASM compatible code being built for a WASM target. Seeing `mio` failing to build is often a sign that none WASM compatible code is being included in the build.
+
+The resolver version can be set in the workspace `Cargo.toml` to remedy this issue.
+
+```toml
+[workspace]
+members = ["member1", "member2"]
+resolver = "2"

+# Defining Routes
+
+## Getting Started
+
+It’s easy to get started with the router.
+
+First things first, make sure you’ve added the `leptos_router` package to your dependencies.
+
+> It’s important that the router is a separate package from `leptos` itself. This means that everything in the router can be defined in user-land code. If you want to create your own router, or use no router, you’re completely free to do that!
+
+And import the relevant types from the router, either with something like
+
+```rust
+use leptos_router::{Route, RouteProps, Router, RouterProps, Routes, RoutesProps};
+```
+
+or simply
+
+```rust
+use leptos_router::*;
+```
+
+## Providing the `<Router/>`
+
+Routing behavior is provided by the [`<Router/>`](https://docs.rs/leptos_router/latest/leptos_router/fn.Router.html) component. This should usually be somewhere near the root of your application, the rest of the app.
+
+> You shouldn’t try to use multiple `<Router/>`s in your app. Remember that the router drives global state: if you have multiple routers, which ones decides what to do when the URL changes?
+
+Let’s start with a simple `<App/>` component using the router:
+
+```rust
+use leptos::*;
+use leptos_router::*;
+
+#[component]
+pub fn App(cx: Scope) -> impl IntoView {
+  view! {
+    <Router>
+      <nav>
+        /* ... */
+      </nav>
+      <main>
+        /* ... */
+      </main>
+    </Router>
+  }
+}
+```
+
+## Defining `<Routes/>`
+
+The [`<Routes/>`](https://docs.rs/leptos_router/latest/leptos_router/fn.Routes.html) component is where you define all the routes to which a user can navigate in your application. Each possible route is defined by a [`<Route/>`](https://docs.rs/leptos_router/latest/leptos_router/fn.Route.html) component.
+
+You should place the `<Routes/>` component at the location within your app where you want routes to be rendered. Everything outside `<Routes/>` will be present on every page, so you can leave things like a navigation bar or menu outside the `<Routes/>`.
+
+```rust
+use leptos::*;
+use leptos_router::*;
+
+#[component]
+pub fn App(cx: Scope) -> impl IntoView {
+  view! {
+    <Router>
+      <nav>
+        /* ... */
+      </nav>
+      <main>
+        // all our routes will appear inside <main>
+        <Routes>
+          /* ... */
+        </Routes>
+      </main>
+    </Router>
+  }
+}
+```
+
+Individual routes are defined by providing children to `<Routes/>` with the `<Route/>` component. `<Route/>` takes a `path` and a `view`. When the current location matches `path`, the `view` will be created and displayed.
+
+The `path` can include
+
+- a static path (`/users`),
+- dynamic, named parameters beginning with a colon (`/:id`),
+- and/or a wildcard beginning with an asterisk (`/user/*any`)
+
+The `view` is a function that takes a `Scope` and returns a view.
+
+```rust
+<Routes>
+  <Route path="/" view=|cx| view! { cx, <Home/> }/>
+  <Route path="/users" view=|cx| view! { cx, <Users/> }/>
+  <Route path="/users/:id" view=|cx| view! { cx, <UserProfile/> }/>
+  <Route path="/*any" view=|cx| view! { cx, <NotFound/> }/>
+</Routes>
+```
+
+> The router scores each route to see how good a match it is, so you can define your routes in any order.
+
+Now if you navigate to `/` or to `/users` you’ll get the home page or the `<Users/>`. If you go to `/users/3` or `/blahblah` you’ll get a user profile or your 404 page (`<NotFound/>`). On every navigation, the router determines which `<Route/>` should be matched, and therefore what content should be displayed where the `<Routes/>` component is defined.
+
+Simple enough?

+# Nested Routing
+
+We just defined the following set of routes:
+
+```rust
+<Routes>
+  <Route path="/" view=|cx| view! { cx, <Home /> }/>
+  <Route path="/users" view=|cx| view! { cx, <Users /> }/>
+  <Route path="/users/:id" view=|cx| view! { cx, <UserProfile /> }/>
+  <Route path="/*any" view=|cx| view! { cx, <NotFound /> }/>
+</Routes>
+```
+
+There’s a certain amount of duplication here: `/users` and `/users/:id`. This is fine for a small app, but you can probably already tell it won’t scale well. Wouldn’t it be nice if we could nest these routes?
+
+Well... you can!
+
+```rust
+<Routes>
+  <Route path="/" view=|cx| view! { cx, <Home /> }/>
+  <Route path="/users" view=|cx| view! { cx, <Users /> }>
+    <Route path=":id" view=|cx| view! { cx, <UserProfile /> }/>
+  </Route>
+  <Route path="/*any" view=|cx| view! { cx, <NotFound /> }/>
+</Routes>
+```
+
+But wait. We’ve just subtly changed what our application does.
+
+The next section is one of the most important in this entire routing section of the guide. Read it carefully, and feel free to ask questions if there’s anything you don’t understand.
+
+# Nested Routes as Layout
+
+Nested routes are a form of layout, not a method of route definition.
+
+Let me put that another way: The goal of defining nested routes is not primarily to avoid repeating yourself when typing out the paths in your route definitions. It is actually to tell the router to display multiple `<Route/>`s on the page at the same time, side by side.
+
+Let’s look back at our practical example.
+
+```rust
+<Routes>
+  <Route path="/users" view=|cx| view! { cx, <Users /> }/>
+  <Route path="/users/:id" view=|cx| view! { cx, <UserProfile /> }/>
+</Routes>
+```
+
+This means:
+
+- If I go to `/users`, I get the `<Users/>` component.
+- If I go to `/users/3`, I get the `<UserProfile/>` component (with the parameter `id` set to `3`; more on that later)
+
+Let’s say I use nested routes instead:
+
+```rust
+<Routes>
+  <Route path="/users" view=|cx| view! { cx, <Users /> }>
+    <Route path=":id" view=|cx| view! { cx, <UserProfile /> }/>
+  </Route>
+</Routes>
+```
+
+This means:
+
+- If I go to `/users/3`, the path matches two `<Route/>`s: `<Users/>` and `<UserProfile/>`.
+- If I go to `/users`, the path is not matched.
+
+I actually need to add a fallback route
+
+```rust
+<Routes>
+  <Route path="/users" view=|cx| view! { cx, <Users /> }>
+    <Route path=":id" view=|cx| view! { cx, <UserProfile /> }/>
+    <Route path="" view=|cx| view! { cx, <NoUser /> }/>
+  </Route>
+</Routes>
+```
+
+Now:
+
+- If I go to `/users/3`, the path matches `<Users/>` and `<UserProfile/>`.
+- If I go to `/users`, the path matches `<Users/>` and `<NoUser/>`.
+
+When I use nested routes, in other words, each **path** can match multiple **routes**: each URL can render the views provided by multiple `<Route/>` components, at the same time, on the same page.
+
+This may be counter-intuitive, but it’s very powerful, for reasons you’ll hopefully see in a few minutes.
+
+## Why Nested Routing?
+
+Why bother with this?
+
+Most web applications contain levels of navigation that correspond to different parts of the layout. For example, in an email app you might have a URL like `/contacts/greg`, which shows a list of contacts on the left of the screen, and contact details for Greg on the right of the screen. The contact list and the contact details should always appear on the screen at the same time. If there’s no contact selected, maybe you want to show a little instructional text.
+
+You can easily define this with nested routes
+
+```rust
+<Routes>
+  <Route path="/contacts" view=|cx| view! { cx, <ContactList/> }>
+    <Route path=":id" view=|cx| view! { cx, <ContactInfo/> }/>
+    <Route path="" view=|cx| view! { cx,
+      <p>"Select a contact to view more info."</p>
+    }/>
+  </Route>
+</Routes>
+```
+
+You can go even deeper. Say you want to have tabs for each contact’s address, email/phone, and your conversations with them. You can add _another_ set of nested routes inside `:id`:
+
+```rust
+<Routes>
+  <Route path="/contacts" view=|cx| view! { cx, <ContactList/> }>
+    <Route path=":id" view=|cx| view! { cx, <ContactInfo/> }>
+      <Route path="" view=|cx| view! { cx, <EmailAndPhone/> }/>
+      <Route path="address" view=|cx| view! { cx, <Address/> }/>

+
+> The main page of the [Remix website](https://remix.run/), a React framework from the creators of React Router, has a great visual example if you scroll down, with three levels of nested routing: Sales > Invoices > an invoice.
+
+## `<Outlet/>`
+
+Parent routes do not automatically render their nested routes. After all, they are just components; they don’t know exactly where they should render their children, and “just stick at at the end of the parent component” is not a great answer.
+
+Instead, you tell a parent component where to render any nested components with an `<Outlet/>` component. The `<Outlet/>` simply renders one of two things:
+
+- if there is no nested route that has been matched, it shows nothing
+- if there is a nested route that has been matched, it shows its `view`
+
+That’s all! But it’s important to know and to remember, because it’s a common source of “Why isn’t this working?” frustration. If you don’t provide an `<Outlet/>`, the nested route won’t be displayed.
+
+```rust
+#[component]
+pub fn ContactList(cx: Scope) -> impl IntoView {
+  let contacts = todo!();
+
+  view! { cx,
+    <div style="display: flex">
+      // the contact list
+      <For each=contacts
+        key=|contact| contact.id
+        view=|cx, contact| todo!()
+      >
+      // the nested child, if any
+      // don’t forget this!
+      <Outlet/>
+    </div>
+  }
+}
+```
+
+## Nested Routing and Performance
+
+All of this is nice, conceptually, but again—what’s the big deal?
+
+Performance.
+
+In a fine-grained reactive library like Leptos, it’s always important to do the least amount of rendering work you can. Because we’re working with real DOM nodes and not diffing a virtual DOM, we want to “rerender” components as infrequently as possible. Nested routing makes this extremely easy.
+
+Imagine my contact list example. If I navigate from Greg to Alice to Bob and back to Greg, the contact information needs to change on each navigation. But the `<ContactList/>` should never be rerendered. Not only does this save on rendering performance, it also maintains state in the UI. For example, if I have a search bar at the top of `<ContactList/>`, navigating from Greg to Alice to Bob won’t clear the search.
+
+In fact, in this case, we don’t even need to rerender the `<Contact/>` component when moving between contacts. The router will just reactively update the `:id` parameter as we navigate, allowing us to make fine-grained updates. As we navigate between contacts, we’ll update single text nodes to change the contact’s name, address, and so on, without doing _any_ additional rerendering.
+
+> This sandbox includes a couple features (like nested routing) discussed in this section and the previous one, and a couple we’ll cover in the rest of this chapter. The router is such an integrated system that it makes sense to provide a single example, so don’t be surprised if there’s anything you don’t understand.

+# Params and Queries
+
+Static paths are useful for distinguishing between different pages, but almost every application wants to pass data through the URL at some point.
+
+There are two ways you can do this:
+
+1. named route **params** like `id` in `/users/:id`
+2. named route **queries** like `q` in `/search?q=Foo`
+
+Because of the way URLs are built, you can access the query from _any_ `<Route/>` view. You can access route params from the `<Route/>` that defines them or any of its nested children.
+
+Accessing params and queries is pretty simple with a couple of hooks:
+
+- [`use_query`](https://docs.rs/leptos_router/latest/leptos_router/fn.use_query.html) or [`use_query_map`](https://docs.rs/leptos_router/latest/leptos_router/fn.use_query_map.html)
+- [`use_params`](https://docs.rs/leptos_router/latest/leptos_router/fn.use_params.html) or [`use_params_map`](https://docs.rs/leptos_router/latest/leptos_router/fn.use_query_map.html)
+
+Each of these comes with a typed option (`use_query` and `use_params`) and an untyped option (`use_query_map` and `use_params_map`).
+
+The untyped versions hold a simple key-value map. To use the typed versions, derive the [`Params`](https://docs.rs/leptos_router/0.2.3/leptos_router/trait.Params.html) trait on a struct.
+
+> `Params` is a very lightweight trait to convert a flat key-value map of strings into a struct by applying `FromStr` to each field. Because of the flat structure of route params and URL queries, it’s significantly less flexible than something like `serde`; it also adds much less weight to your binary.
+
+```rust
+use leptos::*;
+use leptos_router::*;
+
+#[derive(Params)]
+struct ContactParams {
+	id: usize
+}
+
+#[derive(Params)]
+struct ContactSearch {
+	q: String
+}
+```
+
+> Note: The `Params` derive macro is located at `leptos::Params`, and the `Params` trait is at `leptos_router::Params`. If you avoid using glob imports like `use leptos::*;`, make sure you’re importing the right one for the derive macro.
+
+Now we can use them in a component. Imagine a URL that has both params and a query, like `/contacts/:id?q=Search`.
+
+The typed versions return `Memo<Result<T>, _>`. It’s a Memo so it reacts to changes in the URL. It’s a `Result` because the params or query need to be parsed from the URL, and may or may not be valid.
+
+```rust
+let params = use_params::<ContactParams>(cx);
+let query = use_query::<ContactSearch>(cx);
+
+// id: || -> usize
+let id = move || {
+	params.with(|params| {
+		params
+			.map(|params| params.id)
+			.unwrap_or_default()
+	})
+};
+```
+
+The untyped versions return `Memo<ParamsMap>`. Again, it’s memo to react to changes in the URL. [`ParamsMap`](https://docs.rs/leptos_router/0.2.3/leptos_router/struct.ParamsMap.html) behaves a lot like any other map type, with a `.get()` method that returns `Option<&String>`.
+
+```rust
+let params = use_params_map(cx);
+let query = use_query_map(cx);
+
+// id: || -> Option<String>
+let id = move || {
+	params.with(|params| params.get("id").cloned())
+};
+```
+
+This can get a little messy: deriving a signal that wraps an `Option<_>` or `Result<_>` can involve a couple steps. But it’s worth doing this for two reasons:
+
+1. It’s correct, i.e., it forces you to consider the cases, “What if the user doesn’t pass a value for this query field? What if they pass an invalid value?”
+2. It’s performant. Specifically, when you navigate between different paths that match the same `<Route/>` with only params or the query changing, you can get fine-grained updates to different parts of your app without rerendering. For example, navigating between different contacts in our contact-list example does a targeted update to the name field (and eventually contact info) without needing to replacing or rerender the wrapping `<Contact/>`. This is what fine-grained reactivity is for.
+
+> This is the same example from the previous section. The router is such an integrated system that it makes sense to provide a single example highlighting multiple features, even if we haven’t explain them all yet.

+# The `<A/>` Component
+
+Client-side navigation works perfectly fine with ordinary HTML `<a>` elements. The router adds a listener that handles every click on a `<a>` element and tries to handle it on the client side, i.e., without doing another round trip to the server to request HTML. This is what enables the snappy “single-page app” navigations you’re probably familiar with from most modern web apps.
+
+The router will bail out of handling an `<a>` click under a number of situations
+
+- the click event has had `prevent_default()` called on it
+- the <kbd>Meta</kbd>, <kbd>Alt</kbd>, <kbd>Ctrl</kbd>, or <kbd>Shift</kbd> keys were held during click
+- the `<a>` has a `target` or `download` attribute, or `rel="external"`
+- the link has a different origin from the current location
+
+In other words, the router will only try to do a client-side navigation when it’s pretty sure it can handle it, and it will upgrade every `<a>` element to get this special behavior.
+
+The router also provides an [`<A>`](https://docs.rs/leptos_router/latest/leptos_router/fn.A.html) component, which does two additional things:
+
+1. Correctly resolves relative nested routes. Relative routing with ordinary `<a>` tags can be tricky. For example, if you have a route like `/post/:id`, `<A href="1">` will generate the correct relative route, but `<a href="1">` likely will not (depending on where it appears in your view.) `<A/>` resolves routes relative to the path of the nested route within which it appears.
+2. Sets the `aria-current` attribute to `page` if this link is the active link (i.e., it’s a link to the page you’re on). This is helpful for accessibility and for styling. For example, if you want to set the link a different color if it’s a link to the page you’re currently on, you can match this attribute with a CSS selector.
+
+> Once again, this is the same example. Check out the relative `<A/>` components, and take a look at the CSS in `index.html` to see the ARIA-based styling.

+# The `<Form/>` Component
+
+Links and forms sometimes seem completely unrelated. But in fact, they work in very similar ways.
+
+In plain HTML, there are three ways to navigate to another page:
+
+1. An `<a>` element that links to another page. Navigates to the URL in its `href` attribute with the `GET` HTTP method.
+2. A `<form method="GET">`. Navigates to the URL in its `action` attribute with the `GET` HTTP method and the form data from its inputs encoded in the URL query string.
+3. A `<form method="POST">`. Navigates to the URL in its `action` attribute with the `POST` HTTP method and the form data from its inputs encoded in the body of the request.
+
+Since we have a client-side router, we can do client-side link navigations without reloading the page, i.e., without a full round-trip to the server and back. It makes sense that we can do client-side form navigations in the same way.
+
+The router provides a [`<Form>`](https://docs.rs/leptos_router/latest/leptos_router/fn.Form.html) component, which works like the HTML `<form>` element, but uses client-side navigations instead of full page reloads. `<Form/>` works with both `GET` and `POST` requests. With `method="GET"`, it will navigate to the URL encoded in the form data. With `method="POST"` it will make a `POST` request and handle the server’s response.
+
+`<Form/>` provides the basis for some components like `<ActionForm/>` and `<MultiActionForm/>` that we’ll see in later chapters. But it also enables some powerful patterns of its own.
+
+For example, imagine that you want to create a search field that updates search results in real time as the user searches, without a page reload, but that also stores the search in the URL so a user can copy and paste it to share results with someone else.
+
+It turns out that the patterns we’ve learned so far make this easy to implement.
+
+```rust
+async fn fetch_results() {
+	// some async function to fetch our search results
+}
+
+#[component]
+pub fn Search(cx: Scope) -> impl IntoView {
+#[component]
+pub fn FormExample(cx: Scope) -> impl IntoView {
+    // reactive access to URL query strings
+    let query = use_query_map(cx);
+	// search stored as ?q=
+    let search = move || query().get("q").cloned().unwrap_or_default();
+	// a resource driven by the search string
+	let search_results = create_resource(cx, search, fetch_results);
+
+	view! { cx,
+		<Form method="GET" action="">
+			<input type="search" name="search" value=search/>
+			<input type="submit"/>
+		</Form>
+		<Transition fallback=move || ()>
+			/* render search results */
+		</Transition>
+	}
+}
+```
+
+Whenever you click `Submit`, the `<Form/>` will “navigate” to `?q={search}`. But because this navigation is done on the client side, there’s no page flicker or reload. The URL query string changes, which triggers `search` to update. Because `search` is the source signal for the `search_results` resource, this triggers `search_results` to reload its resource. The `<Transition/>` continues displaying the current search results until the new ones have loaded. When they are complete, it switches to displaying the new result.
+
+This is a great pattern. The data flow is extremely clear: all data flows from the URL to the resource into the UI. The current state of the application is stored in the URL, which means you can refresh the page or text the link to a friend and it will show exactly what you’re expecting. And once we introduce server rendering, this pattern will prove to be really fault-tolerant, too: because it uses a `<form>` element and URLs under the hood, it actually works really well without even loading your WASM on the client.
+
+We can actually take it a step further and do something kind of clever:
+
+```rust
+view! { cx,
+	<Form method="GET" action="">
+		<input type="search" name="search" value=search
+			oninput="this.form.requestSubmit()"
+		/>
+	</Form>
+}
+```
+
+You’ll notice that this version drops the `Submit` button. Instead, we add an `oninput` attribute to the input. Note that this is _not_ `on:input`, which would listen for the `input` event and run some Rust code. Without the colon, `oninput` is the plain HTML attribute. So the string is actually a JavaScript string. `this.form` gives us the form the input is attached to. `requestSubmit()` fires the `submit` event on the `<form>`, which is caught by `<Form/>` just as if we had clicked a `Submit` button. Now the form will “navigate” on every keystroke or input to keep the URL (and therefore the search) perfectly in sync with the user’s input as they type.

+# Routing
+
+## The Basics
+
+Routing drives most websites. A router is the answer to the question, “Given this URL, what should appear on the page?”
+
+A URL consists of many parts. For example, the URL `https://leptos.dev/blog/search?q=Search#results` consists of
+
+- a _scheme_: `https`
+- a _domain_: `leptos.dev`
+- a **path**: `/blog/search`
+- a **query** (or **search**): `?q=Search`
+- a _hash_: `#results`
+
+The Leptos Router works with the path and query (`/blog/search?q=Search`). Given this piece of the URL, what should the app render on the page?
+
+## The Philosophy
+
+In most cases, the path should drive what is displayed on the page. From the user’s perspective, for most applications, most major changes in the state of the app should be reflected in the URL. If you copy and paste the URL and open it in another tab, you should find yourself more or less in the same place.
+
+In this sense, the router is really at the heart of the global state management for your application. More than anything else, it drives what is displayed on the page.
+
+The router handles most of this work for you by mapping the current location to particular components.

+# Leptos Starter Template
+
+This is a template demonstrating how to integrate [TailwindCSS](https://tailwindcss.com/) with the [Leptos](https://github.com/leptos-rs/leptos) web framework and the [trunk](https://github.com/thedodd/trunk) tool.
+
+
+Install Tailwind and build the CSS:
+
+`npx tailwindcss -i ./input.css -o ./style/output.css --watch`
+
+Install trunk to client side render this bundle.
+
+`cargo install trunk`
+Then the site can be served with `trunk serve --open`
+
+The browser will automatically open [http://127.0.0.1:8080//](http://127.0.0.1:8080//)
+
+You can begin editing your app at `src/app.rs`.
+
+## Installing Tailwind
+
+You can install Tailwind using `npm`:
+
+```bash
+npm install -D tailwindcss
+```
+
+If you'd rather not use `npm`, you can install the Tailwind binary [here](https://github.com/tailwindlabs/tailwindcss/releases).
+
+## Setting up with VS Code and Additional Tools
+
+If you're using VS Code, add the following to your `settings.json`
+
+```json
+  "emmet.includeLanguages": {
+    "rust": "html",
+    "*.rs": "html"
+  },
+  "tailwindCSS.includeLanguages": {
+      "rust": "html",
+      "*.rs": "html"
+  },
+  "files.associations": {
+      "*.rs": "rust"
+  },
+  "editor.quickSuggestions": {
+    "other": "on",
+    "comments": "on",
+    "strings": true
+  },
+  "css.validate": false,
+```
+
+Install [Tailwind CSS Intellisense](https://marketplace.visualstudio.com/items?itemName=bradlc.vscode-tailwindcss).
+
+    Install "VS Browser" extension, a browser at the right window.
+    Allow vscode Ports forward: 3000, 3001.
+
+## Notes about Tooling
+
+By default, `cargo-leptos` uses `nightly` Rust, `cargo-generate`, and `sass`. If you run into any trouble, you may need to install one or more of these tools.
+
+1. `rustup toolchain install nightly --allow-downgrade` - make sure you have Rust nightly
+2. `rustup default nightly` - setup nightly as default, or you can use rust-toolchain file later on
+3. `rustup target add wasm32-unknown-unknown` - add the ability to compile Rust to WebAssembly
+4. `cargo install cargo-generate` - install `cargo-generate` binary (should be installed automatically in future)
+5. `npm install -g sass` - install `dart-sass` (should be optional in future
+
+
+## Attribution
+This is based on the original Tailwind example (../examples/tailwind)
